Help With Water Parameters

[DJ Monty]

I'm having trouble keeping my Birdsnests alive. I have them under Radions at 35% in different parts of the tank & in different tanks..
My water parameters are like this

Tank 1 220G
Salinity 1.026
Alk 9.0
Calcium 431
PH 7.99
Nitrate 1 0
Phosphorous 50
Temp 80
Magnesium 1400

Tank 2 180G
Salinity 1.026
Alk 10.7
Calcium 420
PH 7.98
Nitrate 1 0
Phosphorous 110
Temp 79.9
Magnesium 1580

Tank 3 60G
Salinity 1.026
Alk 8.1
Calcium 436
PH 7.99
Nitrate 1 0
Phosphorous 123
Temp 80
Magnesium 1460

I know some of these numbers are not good & I'm working on that but which of them should I concentrate on first, if any ?
Thanks

I have several birds nest in my tank and they are at the upper part of the tank where they get good light and flow. That is a requirement for them. Aside from that, you phosphate levels seem very high. Not sure what the measurement is in your note. What are you using to check it? I have a fuge and my phosphates are always zero. I'd like it to be at least .03 ppm but working on it.

You say they are dying... what is giving you that impression? Browning, bleaching, etc?

They are all mid to top level in the tank & have plenty of flow..I'm using a new Hanna Phosphorous checker.. I have a fuge on the 220, the others are just being set up.I seem to be getting some browning & bleaching..I'll try & get some pics up later..
What would be the best way to lower my phosphate ?

I've never had problembs with most birdsnesr in my tanks with higher Nutrients.

Radion at 35% unfortunately doesn't say much about par or intensity.
What size tank. What hanging height and what color mix.

You can also use a lux meter to test intensity.

First tank is 220 gallon, second is 180 gallon & 3rd is 60 gallon.. Radions are mounted on radion mounts which are about 9" above the water.. I use Ecotechs Coral AB+ color mix at 35% intensity....

I don't think that's much light.
